Vertebrate Animal Classification Chart for Grade 2
Vertebrates are animals that have a backbone or spinal column. Let's explore the five main groups of vertebrates:
- Mammals 🐾: Mammals are warm-blooded animals that have hair or fur. They give birth to live young and feed them with milk.
- Birds 🐦: Birds are warm-blooded animals that have feathers and wings. They lay eggs and can usually fly.
- Reptiles 🐍: Reptiles are cold-blooded animals that have scales. They lay eggs and often bask in the sun to stay warm.
- Amphibians 🐸: Amphibians are cold-blooded animals that live part of their lives in water and part on land. They have smooth, moist skin and lay eggs in water.
- Fish 🐠: Fish are cold-blooded animals that live in water. They have fins and gills to help them swim and breathe.
